Not always, kindergartens or nursery located close to the poma. Wearing the baby to the bus or tram on the runes hard, especially in winter. To enter a vehicle with a child and a sled uncomfortable. This situation gave me the idea to make a lightweight collapsible sled. Experience has shown that the design turned out well, lightweight (weighs only 3 kg), simple enough that the kid feels for them perfectly because the seat is made in the form of a chair.
The sled consists of five nodes (see Fig.). The runners from area D-16T 20X20X1,2 mm connected to the front pin М8Х Х370.
All the details — rivets Ø 3-4 mm. seat Cushion, lining soft backrest and apron are constructed from waterproof fabric. The arc handle color stretched vinyl chloride tube.
Fig. 1. General view of the folding sled:

Fig. 2. Looks like the sled in its folded position.
Fig. 3. The Assembly of the sleds (the positions correspond to figure 1)
The springs make installation of the seat into position.
And put the sled so two rings are up, the arc moves forward and leads to the movement of all articulated elements.
When folded, the sled can be moved, clasping his fingers arced handles and pin.
